“…On ultrasound examination they appear as echogenic, non-shadowing masses in the collecting system [2], These radiologic and échographie appearances are nonspecific since a smooth mobile radiolucent filling defect may suggest tumor, urate stone, TBC, blood clots, pyelogenic debris or sloughed papillae [18,19], Computerized tomography rules out nonopaque stones [20], However, a positive clinical his tory in addition to the above-mentioned échographie or…”

“…The normal renal sinus is seen as an area of increased echoes with variable contours due to the fat-parenchyma interface. A collapsed renal pelvis may be indistinguishable from echogenic renal sinus fat (5). Despite good results with US, there are limitations, especially with small lesions when the renal sinus lesion is poorly defined or the echo pattern is similar to or the same as that of the adjacent renal sinus fat or adjacent renal parenchyma (5).…”

Color Doppler US is useful for the evaluation of renal vascular lesions, such as renal artery aneurysm, arteriovenous fistula, and renal vein varix.…”

Various pathologic conditions can occur in the renal sinus, primarily originating in the constituents of the renal sinus, and the renal sinus can be secondarily involved by surrounding renal parenchymal and adjacent retroperitoneal lesions. Lipomatosis and cysts are common renal sinus lesions with little clinical significance, but differentiation from other pathologic conditions is important. Renal vascular lesions such as renal artery aneurysm or arteriovenous fistula can mimic other parapelvic or peripelvic lesions at excretory urography, but their vascular nature is evident at color Doppler ultrasonography, contrast material-enhanced computed tomography (CT), and magnetic resonance (MR) imaging. Although most tumors originating in the renal pelvis are transitional cell carcinoma or squamous cell carcinoma, renal parenchymal tumors such as renal cell carcinoma or benign multilocular cystic nephroma have a tendency to grow into the renal sinus. Rare tumors of mesenchymal origin can develop in the renal sinus, but their imaging findings are nonspecific. The observation of renal sinus fat is important for detecting a small tumor located in that area and determining the exact tumor stage. Multiplanar CT or MR images can allow exact evaluation of the extent of complex renal sinus disease.
